April 2013. Rio de Janeiro; Brazil. "Complexo do Alemão" is a group of favelas in northern Rio.
In November 2010, there was a major security crisis in the Brazilian city of Rio de Janeiro: The Brazilian government sent hundreds of soldiers from the Army and members of the Federal Police Force to further increase security in the city and put the Complexo do Alemão under siege. So far more than 100 vehicles were destroyed and around 40 people killed since the start of the crisis. The President Luís Inácio Lula da Silva declares that the Federal Government fully supports Rio's government to end the situation as soon as possible. Spouses and lawyers of some of the imprisoned leaders of the criminal factions are arrested on suspicion of relaying their orders to start the attacks to their cohorts out of prison.
The Joint task force composed of members of the local police, Army and Marine Corps gives an ultimatum to the criminals at the Complexo do Alemão to surrender while residents evacuate the premisces in spite of the impending invasion. The wave of attacks on civilian targets start to fade.
In November 28 The Complexo do Alemão is taken over by the police with little resistance, but only a few criminals supposed to be hiding in the place are arrested. Further investigations point that the majority managed to escape through rough terrains around the Complex or through a network of illegal water canals built under the favelas.
